community.crypto.acme_inspect – Send direct requests to an ACME server
community.crypto.acme_inspect – Send direct requests to an ACME server
Note
This plugin is part of the community.crypto collection (version 1.3.0).
To install it use: ansible-galaxy collection install community.crypto
.
To use it in a playbook, specify: community.crypto.acme_inspect
.
Synopsis
- Allows to send direct requests to an ACME server with the ACME protocol, which is supported by CAs such as Let’s Encrypt.
- This module can be used to debug failed certificate request attempts, for example when community.crypto.acme_certificate fails or encounters a problem which you wish to investigate.
- The module can also be used to directly access features of an ACME servers which are not yet supported by the Ansible ACME modules.
Requirements
The below requirements are needed on the host that executes this module.
- python >= 2.6
- either openssl or cryptography >= 1.5
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
account_key_content string |
Content of the ACME account RSA or Elliptic Curve key. Mutually exclusive with Required if
In case | |
account_key_src path |
Path to a file containing the ACME account RSA or Elliptic Curve key. Private keys can be created with the community.crypto.openssl_privatekey module. If the requisites (pyOpenSSL or cryptography) are not available, keys can also be created directly with the Mutually exclusive with Required if
| |
account_uri string |
If specified, assumes that the account URI is as given. If the account key does not match this account, or an account with this URI does not exist, the module fails. | |
acme_directory string |
The ACME directory to use. This is the entry point URL to access CA server API. For safety reasons the default is set to the Let's Encrypt staging server (for the ACME v1 protocol). This will create technically correct, but untrusted certificates. The default value is https://acme-staging.api.letsencrypt.org/directory. Note that in community.crypto 2.0.0, this option *will be required* and will no longer have a default. For Let's Encrypt, all staging endpoints can be found here: https://letsencrypt.org/docs/staging-environment/. For Buypass, all endpoints can be found here: https://community.buypass.com/t/63d4ay/buypass-go-ssl-endpoints For Let's Encrypt, the production directory URL for ACME v1 is https://acme-v01.api.letsencrypt.org/directory, and the production directory URL for ACME v2 is https://acme-v02.api.letsencrypt.org/directory. For Buypass, the production directory URL for ACME v2 and v1 is https://api.buypass.com/acme/directory.
| |
acme_version integer |
|
The ACME version of the endpoint. Must be 1 for the classic Let's Encrypt and Buypass ACME endpoints, or 2 for standardized ACME v2 endpoints. The default value is 1. Note that in community.crypto 2.0.0, this option *will be required* and will no longer have a default. Please also note that we will deprecate ACME v1 support eventually. |
content string |
An encoded JSON object which will be sent as the content if method is Required when method is | |
fail_on_acme_error boolean |
|
If method is |
method string |
|
The method to use to access the given URL on the ACME server. The value The value The value |
select_crypto_backend string |
|
Determines which crypto backend to use. The default choice is If set to If set to |
url string |
The URL to send the request to. Must be specified if method is not | |
validate_certs boolean |
|
Whether calls to the ACME directory will validate TLS certificates.
|
Notes
Note
- The account_uri option must be specified for properly authenticated ACME v2 requests (except a
new-account
request). - Using the
ansible
tool, community.crypto.acme_inspect can be used to directly execute ACME requests without the need of writing a playbook. For example, the following command retrieves the ACME account with ID 1 from Let’s Encrypt (assuming/path/to/key
is the correct private account key):ansible localhost -m acme_inspect -a "account_key_src=/path/to/key acme_directory=https://acme-v02.api.letsencrypt.org/directory acme_version=2 account_uri=https://acme-v02.api.letsencrypt.org/acme/acct/1 method=get url=https://acme-v02.api.letsencrypt.org/acme/acct/1%22
- If a new enough version of the
cryptography
library is available (see Requirements for details), it will be used instead of theopenssl
binary. This can be explicitly disabled or enabled with theselect_crypto_backend
option. Note that using theopenssl
binary will be slower and less secure, as private key contents always have to be stored on disk (seeaccount_key_content
). - Although the defaults are chosen so that the module can be used with the Let’s Encrypt CA, the module can in principle be used with any CA providing an ACME endpoint, such as Buypass Go SSL.
